N-bromobutanimide → 9-Bromo-10-phenanthren-3-ylanthracene

Participants

Reaction Steps

30 g (80 mmol) of 9-phenanthren-3-ylanthracene are suspended in 300 ml of THF, 14.2 g (80 mmol) of NBS are added, and the mixture is stirred at RT for 2 h with exclusion of light. The solvent is subsequently removed in vacuo, and the residue is boiled in EtOH and recrystallised twice from dioxane, leaving 32.9 g (95%) of bromide as yellow crystals.
